What about the ivy worms, pest control of the vines / do not misuse insecticides
With the heat of the fragrant vine getting higher and higher, more and more people raise it, but some people who do not pay attention to the breeding methods and matters needing attention will find that there are bugs in their vines. If they are not handled properly, they will not be able to get rid of the bugs, and may also lead to the death of fragrant vines, so what about the ivy worms? The following introduces several correct methods, as well as the matters needing attention in the prevention and control of diseases and insect pests.
What about the fragrant vine worms?
When understanding why the leaves of the vine are yellowing, many people tend to ignore one point, that is, insect pests, which is also one of the reasons for the yellowing of the leaves, so what about the ivy worms? There are three main steps we need to do: the first step is to find out the cause of the insect; the second step is to kill the insect; and the third step is to do a good job in pest control.
1. The cause of the fragrant rattan worm
In general, there are the following reasons: lack of ventilation, poor growth environment, too much watering, insufficient fertilization, and so on, which can be investigated according to the correct planting method and your own actual situation. Because healthy fragrant vines will not grow insects, and such as shielding around, lack of light, too much watering may lead to fragrant rattan worms.
2. Disinfestation
After determining the cause, what about the fragrant vine worms? Reasonable measures need to be taken to get rid of the insects that have grown. The removal mentioned here is not only to remove the visible bugs, but also to remove some invisible eggs, which can be removed in the following ways.
A, if the leaves are deformed, sticky, curled and yellowed, it is very likely that there are aphids, and it may also attract ants. The accurate treatment is to touch the aphids with cotton soaked in alcohol, then spray the aphids with relatively strong mint leaves, and then move the vines outdoors, ventilated and then back indoors.
B, if the caterpillars with oval shell and white wax appear on the vine, they generally appear in the leaf and stem of the plant, and you can use a cotton stick dipped with alcohol to kill insects, and then pay attention to the pest control of the vine.
C, go to the flower point to buy a special anther, and then spray the long worm's fragrant vine, do not use the insecticide commonly used at home, because although this can kill the eggs, it will also cause the leaves to yellowing, because it contains too much concentration.
3. Do a good job in the prevention and control of diseases and insect pests.
After all the previous work has been completed, what we need to pay attention to is to do a good job of prevention and control, because if we ignore it after getting rid of falling insects, we may still have insects again in the future, so prevention is very necessary.
In general, the causes of diseases and insect pests are mainly due to leaf diseases such as leaf spot and leaf blight caused by Cercospora, as well as root rot and stem rot caused by Fusarium. Carbendazim and other drugs can be used for prevention and treatment after death.
The main work for the prevention and control of root rot is that the drainage of the substrate must be good, and the watering should be kept dry and wet alternately, and then put the plants in a bright and slightly higher temperature place, which can well prevent the recurrence of diseases and insect pests.
